If you need to find a bank manager or someone who has important items, wait a few minutes, and the game will display that person in orange through walls. They should be taken hostage, as they sometimes count as civilians, and can easily be found.

Assault waves

Throughout the game, occasionally your contact will say "An assault is coming in X seconds." Listen carefully to what he says. It is a hint of special units coming in, and when the assault will begin. Each wave lasts for approximately five minutes, depending on how many officers you kill. If you need to complete a time consuming objective, such as making sure the saws in the Panic Room are going, camp somewhere near there so you can hold out easier and get the job completed. Note: Some missions have "escape" objectives, which means the wave will never end until you either complete the mission or die. You will know when this happens depending on the mission and what the contact yells.

Special enemies

There are numerous special enemies that can be difficult to kill. You can see them and defeat them more easily by using the shout-out command while aiming at them. Here are some of the enemies and what they do:

Bulldozer: Large bulky enemies covered in thick armor. They do massive damage if they get too close and require a lot of bullets to kill. All fire should be focused on them the moment they are identified. Headshots will help.

Shield: Black officers who have riot shields in front of them and try to move up. They can be flanked easily and taken out from the side and back. Bullets will not harm them in the front. They are very deadly while in a hallway.

Sniper: Although not a "Special Unit", they are deadly. Two shots will drain your health. Either avoid them or take them out.

Spec-Ops: Agents wearing green night-vision goggles. They will handcuff you to the floor if they get too close. It is recommended that you take them out immediately.

Taser: Police who wear yellow stripes. You will hear him charge the tazer before firing at you. If shot, you will be unable to do anything but look around while your character randomly fires at them. Try to aim at them in this state. If tazed for too long, you will go down.
